NR4A1 and atherosclerosis: CircSCRG1 might be a novel angiogenesis target for plaque instability, and the circSCRG1/miR-1268b/NR4A1 axis might regulate angiogenesis in atherosclerosis and mediate the anti-angiogenesis effects of TMP-PF in atherosclerosis in vitro, indicating a novel angiogenesis signalling pathway in atherosclerosis and the regulatory effects of TMP-PF.
